Mermaid syntax reference for writing or fixing a diagram in an artefact: flowchart, sequence, class, state, ER, Gantt, C4, mindmap, timeline and the other diagram types, node shapes, styling, theming, and why a diagram fails to render. Not needed for PlantUML (plantuml-syntax), or when the request is for a governed diagram artefact with document control, which /arckit:diagram produces.

# Mermaid Syntax Reference A comprehensive reference for all 23 Mermaid diagram types plus configuration and theming. This skill provides official Mermaid syntax documentation sourced from the [mermaid-skill](https://github.com/WH-2099/mermaid-skill) project (auto-synced from upstream Mermaid docs). **This skill ships reference material, not runnable scripts.** Read the relevant reference file with `Read`, apply the syntax, and write the diagram into the user's artefact. Do not `Bash`-execute anything from `references/` — they are Mermaid syntax docs, not commands. To look up syntax for a specific diagram type, identify the type from the table below and read the corresponding reference file. ## Supported Diagram Types Select the appropriate diagram type and read the corresponding reference file: | Type | Reference | ArcKit Commands Using It | | ---- | --------- | ------------------------ | | Flowchart | [flowchart.md](references/flowchart.md) | `/arckit:diagram`, `/arckit:dfd`, `/arckit:roadmap`, `/arckit:plan`, `/arckit:backlog`, `/arckit:strategy`, `/arckit:story`, `/arckit:jsp-936` | | Sequence Diagram | [sequenceDiagram.md](references/sequenceDiagram.md) | `/arckit:diagram` | | Class Diagram | [classDiagram.md](references/classDiagram.md) | — | | State Diagram | [stateDiagram.md](references/stateDiagram.md) | — | | ER Diagram | [entityRelationshipDiagram.md](references/entityRelationshipDiagram.md) | `/arckit:data-model` | | Gantt Chart | [gantt.md](references/gantt
